manually setting addon folder?

[Artanox22]

Is there any way to set up addon folder manually? In config or something?

My problem is that I have a name that contains non-latin character.
I can install Minion on a custom location and it opens but I cannot load addon folder.
The problem is that the addon folder is on a path that contains my name (default documents folder).
I can change user name easily but this does not change user folder name.
I do not want to mess up in registry or do other tricks to change user folder name just for this application alone.

Could you please explain me from where the non-latin characters in name requirement come from?
Really, this is basics. I have used alot of custom/user made programs. Nexus mod manager and other Skryim/Fallout mod related programs work perfectly.
